NAME
     sge_schedd - Grid Engine job scheduling agent

SYNOPSIS
     sge_schedd [ -help ]

DESCRIPTION
     <I>sge</I>_<I>schedd</I> computes the  scheduling  decisions  in  an  Grid
     Engine  cluster.  The information necessary for the decision
     is retrieved from <B><A HREF="../htmlman8/sge_qmaster.html">sge_qmaster(8)</A></B>  via  an  event  interface.
     After applying the scheduling algorithm, <I>sge</I>_<I>schedd</I> communi-
     cates the scheduling decision back to  <B><A HREF="../htmlman8/sge_qmaster.html">sge_qmaster(8)</A></B>  again
     via  the  Grid Engine GDI. In order to trigger an <I>sge</I>_<I>schedd</I>
     scheduling run, <B><A HREF="../htmlman8/sge_qmaster.html">sge_qmaster(8)</A></B> samples changes in the  clus-
     ter status and periodically notifies <I>sge</I>_<I>schedd</I>

     By using the -<I>tsm</I> option of the <B><A HREF="../htmlman1/qconf.html">qconf(1)</A></B> command, <I>sge</I>_<I>schedd</I>
     can be forced to print trace messages of its next scheduling
     run to the file &lt;<I>sge</I>_<I>root</I>&gt;/&lt;<I>cell</I>&gt;/<I>common</I>/<I>schedd</I>_<I>runlog</I>.  The
     messages  indicate the reasons for jobs and queues not being
     selected in that run

OPTIONS
     -help
          Print version number of the scheduler.

ENVIRONMENTAL VARIABLES
     SGE_ROOT       Specifies the location  of  the  Grid  Engine
                    standard configuration files.

     SGE_CELL       If set, specifies  the  default  Grid  Engine
                    cell.   To   address   a   Grid  Engine  cell
                    <I>sge</I>_<I>schedd</I> uses (in the order of precedence):

                         The name of the cell  specified  in  the
                         environment  variable SGE_CELL, if it is
                         set.

                         The  name  of  the  default  cell,  i.e.
                         default.


     SGE_DEBUG_LEVEL
                    If  set,  specifies  that  debug  information
                    should  be written to stderr. In addition the
                    level of detail in which debug information is
                    generated is defined.

     SGE_QMASTER_PORT
                    If set,  specifies  the  tcp  port  on  which
                    <B><A HREF="../htmlman8/sge_qmaster.html">sge_qmaster(8)</A></B> is expected to listen for com-
                    munication requests.  Most installations will
                    use  a  services  map  entry  for the service
                    "sge_qmaster" instead to define that port.

FILES
     &lt;<I>sge</I>_<I>root</I>&gt;/&lt;<I>cell</I>&gt;/<I>spool</I>/<I>qmaster</I>/<I>schedd</I>
